Question

The supporting structure of the billboard is attached to the ground by a pin at B, and its rear leg rests on the ground at A. Friction may be neglected. Point G is the centre of the gravity of the billboard and structure, which together weigh 2800 lb. To prevent tipping over in high winds, a 2370-lb weight is placed on the structure near A , as shown. (a) Compute the magnitudes of the reactions at A and B if the wind load on the billboardis q = 120lb/ft. (b) Find the smallest wind loads q that would cause the structure to tip over.
